First, great work! I'll be sending another donation here in a bit.
Second, what useful information could be gained by measuring multiple rig rental places? The reason to compare different multipools is to compare the effectiveness of their coin switching methodology, availability/uptime, and the effectiveness of the pool manager at maintaining the pool.
I understand comparing one RigRental place as a baseline to compare all other multipools against. Other than that, is there a reason that Mh/s rates at "RigRentalA" are going to be that much different than "RigRentalB"? Wouldn't the market equalize that? You could also just look at the previous orders for other's rigs as well (but it wouldn't be as accurate).
(I'm not trying to tell anyone else what do or criticizing others decisions. It's a genuine question.)
Yes, there are differences between rental services, probably even more significant than between multipools. I mean for example CleverMining and WafflePool are nearly identical, and my numbers closely match their published numbers. It's not easy to gauge the effectiveness of a rental service from published numbers. The level of demand can be very different between services, and that affects how often your rig is rented and/or how low do you need to price it to get it rented. If you just look at the past rentals you wouldn't be able to see that, not easily anyway. There is also a difference in how quickly each service reacts to a spike in demand. You mention availability/uptime - that applies to rental services too.
One thing to keep in mind though is that my charts reflect only one of many possible ways - and probably not the most effective - to use these rental services. As I mention in the OP I always try to rent out my rigs as quickly as possible, which means I price them low. Even if there is a pool that pays more than the current rental demand, I will still be renting out instead of switching to that pool, to make sure I can measure the rental income no matter how low it is. I'm sure there are better strategies, e.g. using a rental with a multipool backup, and pricing the rental above the multipool, or maybe combining multiple rental places could yield better results. Also choosing pricing levels (where available, e.g. LeaseRig) and rental duration also can have a significant effect on income.
Then there are factors that can't be reflected on a chart, e.g. the effort required to maintain the rigs for rent. The charts won't - and aren't supposed to - give you a complete picture, but hopefully will provide an incentive to check out some of the options.
Thank you for your support.
